Description

本発明は、移動局から情報を伝送する方法に関するもので、より具体的に、多数のアンテナを含む移動加入局からのアップリンク伝送方法に関するものである。   The present invention relates to a method for transmitting information from a mobile station, and more specifically, to an uplink transmission method from a mobile subscriber station including multiple antennas.

ＩＥＥＥ ８０２．１６ｅの直交周波数分割多重接近（Ｏｒｔｈｏｇｏｎａｌ Ｆｒｅｑｕｅｎｃｙ Ｄｉｖｉｓｉｏｎ Ｍｕｌｔｉｐｌｅｘｉｎｇ Ａｃｃｅｓｓ：ＯＦＤＭＡ）システムにおいて、移動局が３個のアンテナを含む場合、各アンテナ伝送信号の組み合わせを指示する行列が構成される。前記行列は、効果的なアップリンク伝送が発生するように構成される。   In an IEEE 802.16e Orthogonal Frequency Division Multiplexing Access (OFDMA) system, when a mobile station includes three antennas, a matrix indicating a combination of each antenna transmission signal is configured. The matrix is configured such that effective uplink transmission occurs.

基地局または移動局が少なくとも一つのアンテナを含む多重アンテナシステムにおいて、時間ドメイン及び周波数ドメインでのダイバーシティ（ｄｉｖｅｒｓｉｔｙ）利得は、アップリンクまたはダウンリンクにおける各アンテナ伝送信号の結合方式によって変化する。図１は、移動局が２個の伝送アンテナ及び一つの受信アンテナを含む場合、ダイバーシティ利得を得るための例示的な行列を示す。   In a multi-antenna system in which a base station or mobile station includes at least one antenna, the diversity gain in the time domain and the frequency domain varies depending on a combination scheme of each antenna transmission signal in the uplink or the downlink. FIG. 1 illustrates an exemplary matrix for obtaining diversity gain when a mobile station includes two transmit antennas and one receive antenna.

図１に示した行列は、行及び列を含む。行列（ＡまたはＢ）において、行は、伝送順に第１及び第２アンテナ（ＡＮＴ０及びＡＮＴ１）を通して伝送される信号を示し、列は、時間を示す。より具体的に説明すると、行列Ａが用いられる場合、第１及び第２信号（Ｓ１及びＳ２）は、第１チャネルのＡＮＴ０及びＡＮＴ１を通して第１時間フレームに伝送される。引き続いて、次の後続フレームにおける第２及び第１信号（−Ｓ＊ ２及びＳ＊ １）は、第２チャネルのＡＮＴ０及びＡＮＴ１を通して伝送される。ここで、前記第１チャネル及び第２チャネルの受信値をそれぞれｒ０及びｒ１として割り当てることで、受信側は、下記の数学式１によって各シンボルの値を推定することができる。 The matrix shown in FIG. 1 includes rows and columns. In the matrix (A or B), the rows indicate signals transmitted through the first and second antennas (ANT0 and ANT1) in the order of transmission, and the columns indicate time. More specifically, when the matrix A is used, the first and second signals (S 1 and S 2 ) are transmitted in the first time frame through the first channels ANT0 and ANT1. Subsequently, the second and first signals (-S * 2 and S * 1 ) in the next subsequent frame are transmitted through ANT0 and ANT1 of the second channel. Here, by assigning the received values of the first channel and the second channel as r 0 and r 1 , the receiving side can estimate the value of each symbol by the following mathematical formula 1.

上記の式中、ｈ０及びｈ１は、ＡＮＴ０及びＡＮＴ１のチャネル状態をそれぞれ指示する。また、ｈ０及びｈ１は、各アンテナから伝送されるパイロット信号パターンから推定される。
Figure 0004914357
 In the above equation, h 0 and h 1 indicate the channel states of ANT0 and ANT1, respectively. Further, h 0 and h 1 are estimated from pilot signal patterns transmitted from each antenna.

以上の説明は、移動局が３個のアンテナを含むシステムに関連している。図２に示すように、ＩＥＥＥ ８０２．１６ｅのＯＦＤＭＡシステムにおける各行列（Ａ，Ｂ，Ｃ）は、３個のアンテナを含む基地局に基づいて考慮される。ここで、受信側での信号推定方法は、２―アンテナシステムの信号推定方法と類似している。   The above description relates to a system in which the mobile station includes three antennas. As shown in FIG. 2, each matrix (A, B, C) in the IEEE 802.16e OFDMA system is considered based on a base station including three antennas. Here, the signal estimation method on the receiving side is similar to the signal estimation method of the 2-antenna system.

図２に示すように、各行列（Ａ，Ｂ，Ｃ）は、ダウンリンク伝送の間、基地局が３―アンテナを支援する場合に用いられる。しかし、図３に示すように、システムには、アップリンク伝送のために、一緒に３個のアンテナを支援する２個の移動局ＳＳ１，ＳＳ２が含まれる。ここで、第２移動局ＳＳ２が一つのアンテナＡＮＴ２を用いて伝送される反面、第１移動局ＳＳ１は、二つのアンテナＡＮＴ０，ＡＮＴ１を用いて伝送される。２個のアンテナを通して伝送するＳＳ１の結果によると、ＡＮＴ０及びＡＮＴ１が互いに信号を共有できる反面、ＡＮＴ２は信号を共有できない。   As shown in FIG. 2, each matrix (A, B, C) is used when the base station supports 3-antenna during downlink transmission. However, as shown in FIG. 3, the system includes two mobile stations SS1, SS2 that together support three antennas for uplink transmission. Here, the second mobile station SS2 is transmitted using one antenna ANT2, while the first mobile station SS1 is transmitted using two antennas ANT0 and ANT1. According to the result of SS1 transmitted through two antennas, ANT0 and ANT1 can share signals with each other, but ANT2 cannot share signals.

例えば、図２に示す各行列（Ａ，Ｂ，Ｃ）が図３に示す３―アンテナ移動局に適用される場合、ＳＳ１は、Ｓ１及びＳ２をＡＮＴ０及びＡＮＴ１を通してそれぞれ伝送し、ＳＳ２は、Ｓ３及びＳ４をＡＮＴ２を通して独立的に基地局に伝送する。ここで、行列Ａにおいて、ＡＮＴ１がＳ１及びＳ２のみを伝送でき、Ｓ３及びＳ４を伝送できない場合も、Ｓ３及びＳ４が伝送されるので、行列Ａは用いられない。行列Ｂにも、これと同様の限界が適用される。 For example, if each matrix shown in FIG. 2 (A, B, C) is applied to the 3-antenna mobile station shown in FIG. 3, SS1 transmits respectively the S 1 and S 2 through ANT0 and ANT1, the SS2 , transmits the S 3 and S 4 independently in the base station through the ANT2. Here, in the matrix A, ANT1 can be transmitted only S 1 and S 2, may not be able to transmit the S 3 and S 4, since S 3 and S 4 are transmitted, the matrix A is not used. A similar limit applies to the matrix B.

第２移動局がアップリンク伝送のために一つのアンテナを用いる間、アップリンク伝送のために第１移動局が２個のアンテナを用いるシステムには問題点が存在する。図２に示す行列Ａ及び行列Ｂが用いられない。行列Ｃを用いる場合も、時間ドメインでダイバーシティ利得を得られないという問題点を解決できない。   A problem exists in a system in which the first mobile station uses two antennas for uplink transmission while the second mobile station uses one antenna for uplink transmission. The matrix A and the matrix B shown in FIG. 2 are not used. Even when the matrix C is used, the problem that the diversity gain cannot be obtained in the time domain cannot be solved.

本発明は、上記のような従来技術の限界及び不利な点による一つ以上の問題点を実質的に解決するための、多数のアンテナを含む移動加入局からのアップリンク伝送方法と関連している。   The present invention relates to an uplink transmission method from a mobile subscriber station including multiple antennas to substantially solve one or more of the problems due to the limitations and disadvantages of the prior art as described above.

上述した一般的な説明及び後述する本発明の詳細な説明は、例示的及び説明的なもので、請求された発明に対する追加的な説明を提供するだろう。   The foregoing general description and the following detailed description of the invention are exemplary and explanatory and will provide additional explanation for the claimed invention.

本発明は、無線通信システム及び広帯域無線接続システムなどに適用される。   The present invention is applied to a wireless communication system and a broadband wireless connection system.

以下、本発明の実施の形態を、添付の図面に基づいて説明する。図中、同一の図面符号は、同一部分または類似した部分を示す。   Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

本発明の一実施形態は、少なくとも３個のアンテナを含む少なくとも一つの移動局からアップリンクで信号を伝送する方法を提供する。これを達成するために、各アンテナのための伝送信号の組み合わせを示す行列が生成され、生成された行列を用いてアップリンク伝送がなされる。本発明の実施形態は、少なくとも３個のアンテナを含む移動局を支援可能な行列を提供する。例えば、前記行列は、２個のアンテナを含む第１移動局及び一つのアンテナを含む第２移動局を支援することができる。しかしながら、移動局のアンテナ数に対する構成は、上述した構造に制限されない。例えば、一つの移動局が３個のアンテナを含むこともある。   One embodiment of the present invention provides a method for transmitting a signal in the uplink from at least one mobile station including at least three antennas. In order to achieve this, a matrix indicating a combination of transmission signals for each antenna is generated, and uplink transmission is performed using the generated matrix. Embodiments of the present invention provide a matrix that can support a mobile station including at least three antennas. For example, the matrix can support a first mobile station including two antennas and a second mobile station including one antenna. However, the configuration of the mobile station with respect to the number of antennas is not limited to the structure described above. For example, one mobile station may include three antennas.

以上の行列において、ＡＮＴ２がＳ３及びＳ４の独立的な信号のみならず、Ｓ１及びＳ２の信号を伝送する反面、ＡＮＴ０及びＡＮＴ２は、互いに異なる信号（Ｓ１及びＳ２）のみを共有する。 In the above matrix, ANT2 not only independent signals S 3 and S 4, although the transmission signals S 1 and S 2, ANT0 and ANT2 are different signals only (S 1 and S 2) with each other Share.

図３は、３―アンテナシステムの一例で、図４は、３個のアンテナを通して信号を伝送する各移動局を支援する行列を示す一例である。図４に示すように、ＡＮＴ０及びＡＮＴ１を通して伝送される各信号が互いに情報を共有するので、２個のアンテナは、周波数ダイバーシティ利得及び時間ダイバーシティ利得を得るために、伝送の順序を変更することができる。また、ＡＮＴ２を通して伝送される信号がＡＮＴ０及びＡＮＴ１を通して伝送される信号と独立的であるため、Ｓ３は、行列Ｄに示すように反復的に伝送される。また、ｔ時間にＡＮＴ２を通して伝送されるＳ３が受信側で成功的に検出される場合、Ｓ３の代りにＳ４を伝送することで、後続するｔ＋１時間に一層多量の信号が伝送される。ここで、行列の列は、アンテナの順にアンテナ０、１及び２を通して伝送される信号を示し、行列の行は、時間列でのｔ、ｔ＋１時間を示す。 FIG. 3 is an example of a 3-antenna system, and FIG. 4 is an example of a matrix that supports each mobile station transmitting signals through three antennas. As shown in FIG. 4, since the signals transmitted through ANT0 and ANT1 share information with each other, the two antennas can change the order of transmission to obtain frequency diversity gain and time diversity gain. it can. Furthermore, since signals transmitted through the ANT2 is independent and signals transmitted through ANT0 and ANT1, S 3 are repeatedly transmitted as shown in matrix D. Also, if the S 3 transmitted through ANT2 in t time is successfully detected at the receiving side, by transmitting the S 4 instead of S 3, further large amount of signals to a subsequent t + 1 hour is transmitted . Here, the columns of the matrix indicate signals transmitted through the antennas 0, 1, and 2 in the order of antennas, and the rows of the matrix indicate t, t + 1 time in the time column.

図５は、基地局と移動局との間に情報を送信及び受信する動作を示す無線通信システム構造の一例を示す。より具体的に説明すると、制御器１０は、各アンテナから伝送される伝送信号の組み合わせを示す行列を用いて、少なくとも一つの信号を生成する。そして、送信機１４は、前記生成された少なくとも一つの信号を用いてアップリンク信号を伝送する。前記システムは、少なくとも３個のアンテナを含む少なくとも一つの移動局を含み、各移動局は、少なくとも一つのアンテナを含む。また、前記システムは、少なくとも一つの生成信号を用いて伝送されるアップリンク信号を受信する受信機を含む基地局を含む。ここで、前記生成信号は、各アンテナによって伝送される伝送信号の組み合わせを示す行列を用いて生成される。   FIG. 5 shows an example of a wireless communication system structure showing an operation of transmitting and receiving information between a base station and a mobile station. More specifically, the controller 10 generates at least one signal using a matrix indicating a combination of transmission signals transmitted from each antenna. The transmitter 14 transmits an uplink signal using the generated at least one signal. The system includes at least one mobile station including at least three antennas, and each mobile station includes at least one antenna. The system also includes a base station including a receiver that receives an uplink signal transmitted using at least one generated signal. Here, the generated signal is generated using a matrix indicating a combination of transmission signals transmitted by each antenna.

本発明の思想または領域を逸脱しない限り、本発明で多様な修正及び変更が可能であることは、当業者にとって明らかである。したがって、本発明は、添付の特許請求の範囲とその均等範囲内で提供される前記修正及び変更を含む。   It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention.
